Abstract [sv]

Stress påverkar förmågan att fatta beslut. Viss forskning har hittat samband mellan impulsivitet och risktagande på beslutsfattandeuppgifter. Vad som verkar saknas inom området är studier som undersökt om högimpulsivas risktagande under stress skiljer sig från lågimpulsivas risktagande under stress. 18 personer utförde Balloon Analogue Risk Task (BART) två gånger, i två olika situationer; Först i en stressfri situation och sedan i en stressituation. I studien tillämpades en kvasiexperimentell design. Resultatet, som analyserades med en mixed design ANOVA för upprepade mätningar, visade att risktagande på BART ökade under stress. Det fanns inga skillnader i risktagande mellan hög- och lågimpulsiva. Det ökade risktagandet under stress beror troligtvis på ett ökat automatiserat beteende och en förändring av beslutsfattandestrategi.

Abstract [en]

Stress affects the ability to make decisions. Some research has shown a connection between impulsivity and risk-taking on decision-making tasks. What seems to be missing in the area are studies that have examined if high-impulsive individuals differ from low-impulsive individuals regarding risk-taking under stress. 18 participants performed the Balloon Analogue Risk Task (BART) two times, in two different situations; First in a non-stress situation and then in a stressful situation. A quasi-experimental design was applied in this study. The results from a mixed design ANOVA for repeated measures showed that risk-taking on BART increased under stress. There were no differences in risk-taking between the high-impulsive individuals and the low-impulsive individuals. The increased risk-taking under stress is probably due to an increase in automated behaviour and a change in decision-making strategies.
